Description

Technical Field

[0001] The utility model relates to the technical field of fully automatic sealant applicators, in particular to a scraping mechanism for a fully automatic sealant applicator. Background Art

[0002] At present, a sealant applicator is an automated device that specifically controls adhesives and other coatings and drips or coats them on the surface of products. It feeds the coating into the supply hose through compressed air and then, through program control, drips or coats the coating along a pre-set path.

[0003] Application No. CN202223385919.6 discloses a scraping mechanism for a fully automatic sealant applicator, including a frame and a processing table. The processing table is arranged on the surface of the frame. A transverse cylinder is installed on the top cross beam of the frame. The end of the transverse cylinder is connected with a transverse guide rail. A longitudinal guide rail is connected to the transverse guide rail through a slider. A longitudinal cylinder is installed at the top end of the longitudinal guide rail. A sealant pump is installed on the longitudinal guide rail. A glue delivery hose is externally connected to the sealant pump. A blower is arranged on the back of the processing table. The blower is connected with a plurality of air outlets through a shunt conduit, and the air outlets are located inside the support frame of the frame. In the utility model, a scraping plate fixing block can be driven by a telescopic shaft to slide horizontally at the sliding guide rail, so that the scraping plate can scrape the surface of the processing table. The scraping plate is embedded in the hollow groove plate, which is convenient for replacement. This device can conveniently and timely clean the residual glue residues on the surface of the processing table after sealant application.

[0004] The scraping plate is in a fixed posture or can only simply adjust the angle. When facing workpieces to be scraped with complex shapes such as curved surfaces and inclined surfaces, it is easy to have poor fitting between the scraping block and the workpiece surface, resulting in incomplete local scraping, missed scraping, or damage to the scraping block and the workpiece due to hard contact. For workpieces of different sizes and shapes, it is difficult for conventional scraping components to quickly adjust the scraping posture. Summary of the Utility Model

[0005] The purpose of the present invention is to provide a scraping mechanism for a fully automatic sealant applicator to solve the problem of difficult adaptation to complex curved surfaces of different workpieces.

[0006] To solve the above technical problems, the present utility model is realized through the following technical solutions:

[0007] The utility model relates to a glue scraping mechanism of a full-automatic glue applicator, which comprises a numerical control component and a glue scraping structure. The glue scraping structure is installed on the outer wall of one side of the top of the numerical control component. The glue scraping structure comprises a fixed frame. A driving motor is fixedly installed on the outer wall of the right side of the fixed frame. A rotating frame is rotatably connected to the inner walls of both sides of the fixed frame. A glue scraping block is rotatably connected to the inner wall of the bottom surface of the rotating frame. A pulley assembly I is installed at the output end of the driving motor and one side of the rotating frame. A fixed-point rotating block is rotatably connected to the outer wall of the left side of the fixed frame. A rotating motor is fixedly installed on the inner wall of the fixed-point rotating block. A pulley assembly II is installed at the output end of the rotating motor and the output end of the glue scraping block. A limiting groove is formed on the outer wall of the fixed frame at the overlapping position of the pulley assembly II.

[0008] The purpose of such a setting is that during the working process of the glue scraping mechanism, when the numerical control component drives the glue scraping structure to move above the area to be scraped, the driving motor receives a control signal and starts, and the output shaft starts to rotate. The output end of the driving motor is connected to the pulley assembly I. The rotation of the motor is transmitted to one side of the rotating frame through the belt and pulley transmission of the pulley assembly I.

[0009] Both ends of the rotating frame are rotatably connected to the inner walls of both sides of the fixed frame. Driven by the pulley assembly I, the rotating frame swings or adjusts the angle in the fixed frame around the connecting shaft, thereby changing the inclination angle of the glue scraping block and the contact posture with the surface to be scraped, and adapting to the glue scraping requirements of different curved surfaces and inclined surfaces.

[0010] After the rotating frame is adjusted to the basic posture, the rotating motor receives an instruction and starts, and its output shaft rotates. The pulley assembly II is installed at the output end of the rotating motor. The power of the motor is transmitted to the rotating shaft of the glue scraping block through the belt and pulley of the pulley assembly II.

[0011] The inner wall of the bottom surface of the glue scraping block is rotatably connected to the rotating frame. Driven by the pulley assembly II, the glue scraping block rotates around its own axis to perform glue scraping operation on the lower glue application area. At the same time, the limiting groove on the fixed frame is stuck at the overlapping position of the pulley assembly II to limit the lateral displacement of the pulley assembly II, avoid belt deviation, ensure stable transmission, and make the rotation trajectory and glue scraping force of the glue scraping block more uniform. During the glue scraping process, the driving motor can continuously fine-tune the posture of the rotating frame according to the real-time shape and angle change of the surface to be scraped, and the rotating motor synchronously cooperates to adjust the rotation speed and angle of the glue scraping block. The two cooperate to complete the full-automatic glue scraping of complex surfaces. After a single glue scraping is completed, the driving motor and the rotating motor can be reset, waiting for the numerical control component to drive the glue scraping structure to move to the next working position and repeat the above process.

[0012] The driving motor cooperates with the pulley assembly one, enabling the rotating frame to drive the rubber scraping block to flexibly change its posture, so as to adapt to glue application surfaces of different shapes and angles, improving the adaptability of rubber scraping. The rotating motor, pulley assembly two and the limit groove work together to make the rubber scraping block rotate itself and be restricted in position, ensuring uniform rubber scraping and improving the surface quality after glue application.

[0013] Further, the numerical control component includes a machine tool. An operation panel is provided on the upper surface of the machine tool, and a bidirectional lead screw assembly is installed on the inner walls on both sides of the machine tool.

[0014] The purpose of such a setting is that during the operation of the rubber scraping mechanism, the machine tool provides the basic support for the equipment, the operation panel is used to input instructions and parameters, and the bidirectional lead screw assembly provides the driving basis for the movement of the movable frame.

[0015] Further, movable frames are installed on the outer walls on both sides of the top of the bidirectional lead screw assembly. A motor one is fixedly installed on the outer wall in the middle of the tail end of the machine tool, and the output end of the motor one is connected to the movable frame through the bidirectional lead screw assembly.

[0016] The purpose of such a setting is that during the operation of the rubber scraping mechanism, when the motor one starts, it drives the bidirectional lead screw assembly to operate, driving the movable frame to move towards or away from each other along the inner walls on both sides of the machine tool, adjusting the distance between the movable frames.

[0017] Further, a transverse lead screw assembly is installed on the inner walls on both sides of the top of the movable frame, and a mounting plate is sleeved on the outer wall of the transverse lead screw assembly.

[0018] The purpose of such a setting is that during the operation of the rubber scraping mechanism, the transverse lead screw assembly operates on the top of the movable frame, driving the mounting plate to move along the length direction of the transverse lead screw assembly, adjusting the transverse position of the mounting plate.

[0019] Further, a vertical lead screw assembly is vertically installed on the inner wall of the mounting plate. A slider is sleeved on the rod body of the vertical lead screw assembly, and the upper and lower ends of the slider are slidably connected to the upper and lower side rails of the mounting plate.

[0020] The purpose of such a setting is that during the operation of the rubber scraping mechanism, the vertical lead screw assembly works, enabling the slider to slide in the vertical direction along the upper and lower side rails of the mounting plate, changing the vertical height of the slider and the subsequent connected components.

[0021] Further, an installation panel is provided at the front end of the slider, and the fixed frame is fixedly installed on the lower surface of the installation panel.

[0022] The purpose of such a setting is that during the operation of the rubber scraping mechanism, the installation panel serves as the installation carrier of the fixed frame, connecting the rubber scraping structure to the slider and adjusting the position of the rubber scraping structure along with the movement of the slider.

[0023] The utility model has the following beneficial effects:

[0024] (1) Through the settings of the pulley assembly, driving motor and rotating motor in the utility model, the driving motor cooperates with the pulley assembly one, enabling the rotating frame to drive the rubber scraping block to flexibly change its posture, which can adapt to rubberizing surfaces of different shapes and angles, improving the adaptability of rubber scraping. The rotating motor, pulley assembly two and the limiting groove work together to make the rubber scraping block rotate itself and its position is restricted, ensuring uniform rubber scraping and improving the surface quality after rubberizing.

[0025] (2) Through the settings of the vertical lead screw assembly and the mounting plate in the utility model, when the vertical lead screw assembly works, the slider slides vertically along the upper and lower side rails of the mounting plate. The mounting panel serves as the mounting carrier of the fixing frame, connects the rubber scraping structure with the slider, and adjusts the position of the rubber scraping structure as the slider moves.

[0026] Of course, it is not necessary for any product implementing the utility model to simultaneously achieve all the above-mentioned advantages. Description of the Drawings

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1-4 As shown, the present invention is a scraping mechanism for a full-automatic sealant applicator, including a numerical control component 1 and a scraping structure 2. The scraping structure 2 is installed on the outer wall of one side of the top of the numerical control component 1. The scraping structure 2 includes a fixed frame 201. A driving motor 202 is fixedly installed on the outer wall of the right side of the fixed frame 201. Rotating frames 204 are rotatably connected to the inner walls on both sides of the fixed frame 201. A scraping block 210 is rotatably connected to the inner wall of the bottom surface of the rotating frame 204. A pulley assembly one 203 is installed between the output end of the driving motor 202 and one side of the rotating frame 204. A fixed-point rotating block 205 is rotatably connected to the outer wall of the left side of the fixed frame 201. A rotating motor 206 is fixedly installed on the inner wall of the fixed-point rotating block 205. A pulley assembly two 207 is installed between the output end of the rotating motor 206 and the output end of the scraping block 210. A limiting groove 209 is opened on the outer wall of the fixed frame 201 at the overlapping position of the pulley assembly two 207.

[0036] The purpose of such a setting is that during the working process of the scraping mechanism, when the numerical control component 1 drives the scraping structure 2 to move above the area to be scraped, the driving motor 202 receives a control signal and starts, and the output shaft starts to rotate. The output end of the driving motor 202 is connected to the pulley assembly one 203, and the rotation of the motor is transmitted to one side of the rotating frame 204 through the belt and pulley transmission of the pulley assembly one 203;

[0037] Both ends of the rotating frame 204 are rotatably connected to the inner walls on both sides of the fixed frame 201. Driven by the pulley assembly one 203, it swings or adjusts the angle around the connecting shaft in the fixed frame 201, thereby changing the inclination angle of the scraping block 210 and the contact posture with the surface to be scraped, and adapting to the scraping requirements of different curved surfaces and inclined surfaces;

[0038] After the rotating frame 204 is adjusted to the basic posture, the rotating motor 206 receives an instruction and starts, and its output shaft rotates. The pulley assembly two 207 is installed at the output end of the rotating motor 206, and the power of the motor is transmitted to the rotating shaft of the scraping block 210 through the belt and pulley of the pulley assembly two 207,

[0039] The inner wall of the bottom surface of the scraping block 210 is rotatably connected to the rotating frame 204. Driven by the pulley assembly two 207, it rotates around its own axis to perform scraping operation on the lower gluing area. At the same time, the limiting groove 209 on the fixed frame 201 is stuck at the overlapping part of the pulley assembly two 207, restricting the lateral displacement of the pulley assembly two 207, avoiding belt deviation, ensuring stable transmission, and making the rotation trajectory and scraping force of the scraping block 210 more uniform. During the scraping process, the driving motor 202 can continuously fine-tune the posture of the rotating frame 204 according to the real-time shape and angle change of the surface to be scraped, and the rotating motor 206 synchronously cooperates to adjust the rotation speed and angle of the scraping block 210. The two cooperate to complete the full-automatic scraping of complex surfaces. After a single scraping is completed, the driving motor 202 and the rotating motor 206 can be reset, waiting for the numerical control component 1 to drive the scraping structure 2 to move to the next working position and repeat the above process;

[0040] The driving motor 202 cooperates with the pulley assembly one 203 to enable the rotating frame 204 to drive the scraping block 210 to flexibly change its posture, adapt to gluing surfaces of different shapes and angles, and improve the scraping adaptability. The rotating motor 206, the pulley assembly two 207 and the limiting groove 209 cooperate to limit the self-rotation and position of the scraping block 210, ensure uniform scraping and improve the surface quality after gluing.

[0041] The numerical control component 1 includes a machine tool 101. An operation panel 103 is provided on the upper surface of the machine tool 101, and a bidirectional lead screw assembly 102 is installed on the inner walls on both sides of the machine tool 101.

[0042] The purpose of such a setting is that during the working process of this scraping mechanism, the machine tool 101 provides the basic support for the equipment, the operation panel 103 is used to input instructions and parameters, and the bidirectional lead screw assembly 102 provides the transmission basis for the movement of the movable frame 105.

[0043] Movable frames 105 are installed on the outer walls on both sides of the top of the bidirectional lead screw assembly 102, and a motor one 104 is fixedly installed on the outer wall in the middle of the tail end of the machine tool 101. The output end of the motor one 104 is connected to the movable frame 105 through the bidirectional lead screw assembly 102.

[0044] The purpose of such a setting is that during the working process of this scraping mechanism, when the motor one 104 is started, it drives the bidirectional lead screw assembly 102 to operate, driving the movable frame 105 to move towards or away from each other along the inner walls on both sides of the machine tool 101 to adjust the distance between the movable frames 105.

[0045] Transverse lead screw assemblies 106 are installed on the inner walls on both sides of the top of the movable frame 105, and a mounting plate 107 is sleeved on the outer wall of the transverse lead screw assemblies 106.

[0046] The purpose of such a setting is that during the operation of the glue scraping mechanism, the transverse lead screw assembly 106 rotates on the top of the movable frame 105, driving the mounting plate 107 to move along the length direction of the transverse lead screw assembly 106 to adjust the transverse position of the mounting plate 107.

[0047] A vertical lead screw assembly 108 is vertically installed on the inner wall of the mounting plate 107. A slider 109 is sleeved on the rod body of the vertical lead screw assembly 108, and the upper and lower ends of the slider 109 are slidably connected to the upper and lower side rails of the mounting plate 107.

[0048] The purpose of such a setting is that during the operation of the glue scraping mechanism, the vertical lead screw assembly 108 works, causing the slider 109 to slide vertically along the upper and lower side rails of the mounting plate 107, changing the vertical height of the slider 109 and subsequent connected components.

[0049] An installation panel 110 is provided at the front end of the slider 109, and the fixing frame 201 is fixedly installed on the lower surface of the installation panel 110.

[0050] The purpose of such a setting is that during the operation of the glue scraping mechanism, the installation panel 110 serves as the installation carrier of the fixing frame 201, connecting the glue scraping structure 2 to the slider 109 and adjusting the position of the glue scraping structure 2 as the slider 109 moves.

[0051] During use, the first motor 104 receives a system instruction to start, the output shaft rotates, driving the lead screw of the bidirectional lead screw assembly 102 to rotate. The two ends of the lead screw of the bidirectional lead screw assembly 102 have reverse threads. When the lead screw rotates, the two side movable frames 105 move towards / away from each other along the inner wall rails of the machine tool 101 according to the width of the workpiece to adjust the spacing until the spacing of the movable frames 105 adapts to the placement width of the workpiece, making a basic positioning for subsequent horizontal and vertical adjustments;

[0052] The transverse lead screw assembly 106 at the top of the movable frame 105 starts, the lead screw rotates, and the mounting plate 107 is sleeved on the outer wall of the lead screw of the transverse lead screw assembly 106. When the lead screw rotates, the mounting plate 107 moves horizontally along the length direction of the transverse lead screw assembly 106, driving the glue scraping structure 2 close to the transverse coordinate position of the area to be scraped with glue, and initially aligning with the starting point of glue scraping of the workpiece;

[0054] The numerical control component 1 drives the glue scraping structure 2 to move above the area to be scraped with glue. The system sends an attitude adjustment instruction to the drive motor 202 according to the curvature of the workpiece surface, such as a curved surface or an inclined surface. The drive motor 202 starts, and the output shaft rotates to drive the first pulley assembly 203 to operate; through the belt drive of the first pulley assembly 203, the power is transmitted to one side of the rotating frame 204, causing the rotating frame 204 to swing / tilt around the connecting shafts on both inner walls of the fixed frame 201, changing the contact angle between the glue scraping block 210 and the surface to be scraped with glue, and completing the fine adaptation of the glue scraping attitude.

[0055] After the attitude of the rotating frame 204 is adapted, the system sends a glue scraping instruction to the rotating motor 206. The rotating motor 206 starts, and the output shaft rotates. The output shaft of the rotating motor 206 transmits the power to the rotating shaft of the glue scraping block 210 through the second pulley assembly 207, causing the glue scraping block 210 to rotate around its own axis; at the same time, the limiting groove 209 on the fixed frame 201 is stuck at the overlapping part of the second pulley assembly 207, restricting the lateral displacement of the belt, avoiding belt slipping and deviation, and ensuring the stable rotation of the glue scraping block 210 and the uniform glue scraping force.
